ORACLE RAC无db删除、创建、增加磁盘组

一、删除

dismount磁盘组

alter diskgroup data01 dismount;

drop磁盘组

drop diskgroup data01 force including contents;

crs删除磁盘组

crsctl stat res -t   #删除前查看资源状况
srvctl remove diskgroup -g data01
crsctl stat res -t   #删除后查看资源状况

二、创建

查看os上磁盘信息

upadmin show vlun

lvmdiskscan

创建磁盘组

create diskgroup data01 normal redundancy failgroup FGA disk '/dev/asmdisks/sdc1' failgroup FGB disk '/dev/asmdisks/sdec1' ATTRIBUTE 'compatible.asm' = '11.2', 'compatible.rdbms' = '11.2','au_size'='4M';

三、增加

alter diskgroup data01 add failgroup FGA disk '/dev/asmdisks/sdbg1','/dev/asmdisks/sdbh1'  failgroup FGB disk '/dev/asmdisks/sdgg1','/dev/asmdisks/sdgh1';
